Odin Rqtclose: !full!

After the patch, the rqtclose behavior vanished. The keyword "odin rqtclose" is not a command you type—it is a symptom. It represents the unintended termination of ODIN nodes or the rqt GUI due to lifecycle mismatches, resource exhaustion, signal handling errors, or software bugs. By understanding the architectural layers (DDS, ROS 2, Qt, and ODIN's lifecycle hooks), you can diagnose and fix the problem systematically. odin rqtclose

Patch odin_sonar.cpp to check for null pointers in the diagnostic publisher: def shutdown_odin(self): # Call the ODIN service that
